Abstract: The general problems concerning air contamination monitoring in the environment of nuclear plants are briefly discussed. The environmental survey of the Jülich Nuclear Research Center serves as an example to demonstrate, which methods can be applied in practice to solve the problems, arising in monitoring waste air. The air monitoring system at Jülich essentially consists of a central measuring station and two monitoring rings surrounding the plant at different distances. The inner ring as the most important sub-system is discussed in some more detail. By evaluations of the activity emissions in the case of reactor accidents and of the dispersion depending on the meteorological conditions, the magnitude of environmental contamination is estimated and reasons are given for number and location of the measuring stations of the inner monitoring ring. A review is given of the main measuring methods applied at Jülich, with which an air survey can be executed from the normal background up to the maximum credible accident values. A special aerosol measuring, instrument with intermittent transport of filter tape and threedetectorsis described which makes it possible to determine the instantaneous aerosol activity, its long-lived fraction after several days, and the effective half-life after a few hours.
